By the midpoint formula, we can get the coordinates of D: ( (x_2+x_2)2, (y_2+y_2)2).Since G is the centroid of the triangle ABC, we know that AG:GD=2:1.In other words, λ = (AG)(GD)=2.Using the formula x= (x_1+λ x_2)(1+λ ) and y= (y_1+λ y_2)(1...

We have already seen that the three perpendicular bisectors of the sides of a triangle meet at a common point which is the center of its circumcircle:This is true because points on a perpendicular bisector are equidistant from the endpoints of the segment it bisects, so the intersection of ...
A B C is a triangle. G is the centroid. The line parallel to B C through G meets A B at B'and A C at C'. Let A " be the midpoint of BC, C" the intersection of B' C and BG, and B"the intersection of C' B and CG. Prove that A" B "C" is similar to ABC. ...
